EFFICIENT MINING OF NON-REDUNDANT PERIODIC FREQUENT PATTERNS

Efficient Mining of Non-Redundant Periodic Frequent Patterns

Periodic frequent patterns are frequent patterns which occur at periodic intervals in databases.They are useful in decision making where event occurrence intervals are vital.Traditional algorithms for discovering periodic frequent patterns, however, often report a large number Terminal Blocks of such patterns, most of which are often redundant as t

Influences of TiO2 or Y2O3 doping on the homogeneity of polycrystalline Al2O3 produced by pulsed electric current sintering

Influences of TiO2 or Y2O3 dopants on pressure-assisted sintering of polycrystalline Al2O3 were investigated to control the microstructure of sintered Al2O3 as well as to improve the homogeneity of transparent Al2O3 samples.The transparent polycrystalline Al2O3 samples with and without the dopants were fabricated by two-step pulsed electric current
